Mold often develops after a water loss.
A pipe leaks. A roof allows water inside. A supply line fails. Drying is delayed or incomplete, and mold appears days or weeks later.
When that happens, the insurance company may treat the mold as a separate issue, apply a mold limitation or exclusion, or argue that the condition resulted from humidity, maintenance, or long-term moisture rather than the original water event.
The cause matters.
Biohazard and contamination claims can raise similar questions. Sewage backups, biological contamination, and other hazardous conditions may require specialized cleanup, removal of affected materials, testing, and reconstruction.
We review the original cause of the loss, the extent of the contamination, the remediation records, and the policy to determine what coverage may apply.
Common Issues in Mold and Biohazard Claims
The cause of the mold. The insurance company may attribute mold to humidity, maintenance, condensation, or long-term moisture instead of a covered water event. Plumbing records, photographs, moisture readings, and the timing of the loss can become important.
Mold limits and exclusions. Many policies contain special provisions addressing mold, fungi, bacteria, or microbial growth. Whether a limitation applies, and what expenses fall within it, depends on the specific policy language and the circumstances of the loss.
Incomplete remediation scope. A remediation estimate may address cleaning or treatment without accounting for demolition, removal of contaminated materials, access, reconstruction, or other work necessary to restore the property.
Disputes over the extent of contamination. Mold, sewage, and other contaminants can spread beyond what is immediately visible. Moisture mapping, environmental assessment, testing, and remediation protocols may be needed to determine the full scope.
Clearance and reconstruction. Removing contamination is only part of the process. Depending on the loss, the property may also require post-remediation verification and reconstruction of walls, flooring, cabinetry, insulation, or other materials that were removed.
How We Review a Mold or Biohazard Claim
We begin with the event that caused the condition.
For mold claims, that may mean reviewing the underlying water loss, plumbing records, roof damage, mitigation documents, photographs, moisture readings, and the timeline of when the mold appeared.
For biohazard or contamination claims, we may review environmental reports, remediation protocols, sewage or plumbing records, testing results, contractor estimates, and the insurance company’s coverage position.
We then examine the policy provisions the insurance company is relying on, including any mold, fungi, bacteria, pollution, contamination, water, or sewage-related terms.
The scope of the loss matters as much as the cause. We review not only the cost of remediation, but also demolition, removal, access, drying, clearance testing, and reconstruction where those items are part of the covered damage.
The goal is to determine whether the insurance company properly identified the cause of the condition and correctly applied the policy to the full scope of the loss.
